AI-suggested
An official fix is available and has been released by Ubuntu as part of their Linux kernel security updates. Users should apply the updated kernel packages to versions equal to or greater than 5.15.0-1103.110~20.04.1, 5.15.0-1110.119~20.04.1, 5.15.0-1103.112~20.04.1, 5.15.0-173.183~20.04.1, and 5.15.0-1097.100~20.04.1. No additional mitigation is required once the patch is applied.
Description
A use-after-free vulnerability was fixed in the Linux kernel's scsi aic94xx driver. The issue occurs in the asd_pci_remove() function, which fails to synchronize with pending tasklets before freeing the asd_ha structure during device removal, potentially leading to use-after-free conditions. The fix involves adding tasklet_kill() to ensure all scheduled tasklets complete before cleanup. This vulnerability affects certain Ubuntu Linux kernel versions prior to specific 5.15.0 updates.
